Tissue Repair Device with Audible Click Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tissue repair devices often misfire, leading to unpredictable deployment and increased risk of damage during surgical procedures, particularly in difficult-to-access areas like the knee joint, requiring highly skilled surgeons and complete immobilization of the surgical area.
Innovation Solution
A tissue repair device with a handle, depth control sheath, and needle that allows for ergonomic single-handed deployment of implants, featuring a selector knob to prevent misfire, a deployment knob for secure implant placement, and an audible click feedback mechanism to confirm deployment, along with a cinching mechanism for secure knot construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional devices are used for tissue repair, then the repair function is achieved, but misfire and unpredictable deployment occur
Solution Approach 1:
The device incorporates an audible click feedback mechanism that provides tactile and auditory confirmation when the selector knob reaches the correct position, eliminating uncertainty in implant deployment and preventing misfire while maintaining simple single-handed operation
Solution Approach 2:
The selector knob mechanism automatically positions itself through audible click feedback, allowing the device to self-confirm proper positioning without requiring additional verification steps or complex operational procedures from the surgeon
2Reliability
If existing repair methods are used, then tissue repair is performed, but complete immobilization of the surgical area is required
Solution Approach 1:
The device deploys implants in a predetermined sequence through the selector knob mechanism, ensuring proper tissue approximation and stabilization before releasing the surgical area, thereby securing healing while enabling faster surgical throughput
3Manufacturing precision
If conventional deployment mechanisms are used, then implants are placed, but slippage of the last implant occurs
Solution Approach 1:
The audible click feedback mechanism confirms each implant deployment step, including the final implant, providing tactile and auditory verification that prevents slippage while maintaining simple single-handed operation throughout the procedure
4Object-affected harmful factors
If arthroscopic techniques are used, then incision size is reduced, but highly skilled surgeons are required
Solution Approach 1:
The device with its self-confirming audible click feedback mechanism and automatic positioning features performs the complex positioning and deployment functions autonomously, reducing the skill barrier for arthroscopic procedures while maintaining minimal incision benefits
